Measurement of night sky brightness in southern Australia
, 2011 Night sky brightness is a major source of noise both for Cherenkov telescopes as well as for wide-angle Cherenkov detectors. Therefore, it is important to know the level of night sky brightness at potential sites for future experiments.

Sky Variability in the y Band at the LSST Site [PDF]
, 2010 We have measured spatial and temporal variability in the y band sky brightness over the course of four nights above Cerro Tololo near Cerro Pachon, Chile, the planned site for the Large Synoptic Survey Telescope (LSST).

Anthropogenic disruption of the night sky darkness in urban and rural areas [PDF]
Royal Society Open Science, 2016 The growing emissions of artificial light to the atmosphere are producing, among other effects, a significant increase of the night sky brightness (NSB) above its expected natural values. A permanent sensor network has been deployed in Galicia (northwest

Laboratory Characterisation of a Commercial RGB CMOS Camera for Measuring Night Sky Brightness
Remote Sensing, 2023 The use of RGB cameras in photometric applications has grown over the last few decades in many fields such as industrial applications, light engineering and the analysis of the quality of the night sky.

Optical Sky Brightness at Cerro Tololo Inter-American Observatory from 1992 to 2006
, 2007 We present optical UBVRI sky brightness measures from 1992 through 2006. The data are based on CCD imagery obtained with the CTIO 0.9-m, 1.3-m, and 1.5-m telescopes.

Artificial light alters natural regimes of night-time sky brightness [PDF]
, 2015 PMCID: PMC3634108Open access journalArtificial light is globally one of the most widely distributed forms of anthropogenic pollution. However, while both the nature and ecological effects of direct artificial lighting are increasingly well documented ...

Measuring Light Pollution with Fisheye Lens Imagery from A Moving Boat, A Proof of Concept [PDF]
, 2017 Near all-sky imaging photometry was performed from a boat on the Gulf of Aqaba to measure the night sky brightness in a coastal environment. The boat was not anchored, and therefore drifted and rocked.

The Spectrum of the Night Sky Over Kitt Peak: Changes Over Two Decades
, 2010 New absolute spectrophotometry of the Kitt Peak night sky has been obtained in 2009/10, which we compare to previously published data obtained in 1988 and 1999, allowing us to look for changes over the past two decades.

Optical Night-Sky Brightness at Mauna Kea over the Course of a Complete Sunspot Cycle [PDF]
, 1997 We have produced a data base of V-band and B-band night-sky brightness measurements rather evenly spread out over the course of a whole sunspot cycle from September 1985 to August 1996.
